I followed the instructions and encountered a little problem with genicam
This is error:

Traceback (most recent call last):
  File "trash_classifier.py", line 25, in <module>
    camera = pylon.InstantCamera(pylon.TlFactory.GetInstance().CreateFirstDevice())
  File "/home/trungluc12706/.local/lib/python3.6/site-packages/pypylon/pylon.py", line 1614, in CreateFirstDevice
    return _pylon.TlFactory_CreateFirstDevice(self, *args)
